Edit the parsed version.
First save! You may use HTTP?-PUT? (behind the save
or publish publish button of you browser/editor)
to commit your changes there.
Bug: when you use the create button, changes
will be saved, but the old values will be used to actually
create the document.

This version is functionally equivalent to the next (at least
for the purpose here) and it's somewhat more readable.
Knowledge about optimizations in mechanism/tree.scm motivates
the more complicated form below. Reason: the "data" function
returns the string from a xml literal if applied to a node list
of just one literal. For a list of xml elements (like the
result of select-elements here) it will apply string-append
recursivly to compute the value. This is not nessesary, we know
there's just one string.

<!-- fold-links gibt eine Funktion mit zwei Parametern,
einem Kombinator und einem Initialwert. Der Kombinator
wird für alle Links auf den Link und den akkumulierten Initialwert
andgewendet, d.h. ergibt den neuen Initialwert für den nächsten Link.
Hier, im einfachsten Fall, wird als Kombinator 'cons' verwendet
und die leere Liste als Initalwert. Damit wird jeder Link
vor die Liste gehängt, mithin erhalten wir eine Liste aller Links.
Braucht man nur einige, dann ist 'cons' entsprechend zu ersetzen.
